She called from the road last week, saying she was headed home to Salem from Reno. "Just thought you'd like to know," the woman on the voice mail said, "there seems to be construction at every town along I-5. Ashland, Medford, Roseburg ... you name it."

Yep, it's going to be that kind of summer.

Oregon's busiest road-construction season in 50 years will be fueled by federal economic stimulus money and the Oregon Transportation Investment Act, a series of funding packages that raised $2.96 billion for highway and bridge construction work.

In the Portland area, there will be 13 highway projects, more than three times as many as last summer. To help you make sense of it all, we've provided this handy-dandy map.

Statewide, the Oregon Department of Transportation says there will be 141 projects. That's more map (and dots) than we have room for here. But you can download a map with the whole enchilada -- locations, details, schedules -- at The Oregonian's Hard Drive commuting blog: oregonlive.com/harddrive.

How many traffic jams will this summer of construction love create?

"Very few," said ODOT spokeswoman Christine Miles. "Most of them are going to be nighttime work."
